DESCRIPTION

14       Returns  the usual height of a line of text in the specified font.  For
15       bitmap fonts this is simply the height of all glyph bitmaps.  For true‐
16       type fonts it is whatever the font file specifies.  In particular, some
17       special glyphs may be higher than the height returned here.
18
19       If the X is the position you specify  to  draw  text,  the  meaning  of
20       ascent and descent and the line height is like in the figure below.
